You should use wait() to find out if the process is alive, not tricks

I'm not sure I can do that because the process I'm interested in isn't a
child of mine.
wait() doesn't work then. But why it isn't a child?
In any case, I'd still need to use the process name to make sure the PID
belongs to the original process, because PIDs are reused after a while.
No. If it is your child the process continue to exist as zombie until
you've asked for the exit status using wait().
